Current Reflection and Transmission at Conformal Defects Applying BCFT to Transport Process [PDF]

, 2014
International audienceWe study reflection/transmission process at conformal defects by introducing new transport coefficients for conserved currents. These coefficients are defined by using BCFT techniques thanks to the folding trick, which turns the ...

Os problemas de espalhamento quântico em potenciais elementares

Revista Brasileira de Ensino de Física
Neste trabalho estudamos o espalhamento quântico de uma partícula por um potencial generalizado que engloba em si todas as formas de potenciais retangulares unidimensionais. Neste contexto nós calculamos as probabilidades de reflexão e transmissão de uma

Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

Advanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

Research into connection between spectral resonance structures and harmonics of ionospheric Alfvén resonator

Solar-Terrestrial Physics, 2018
We present the results of modeling of the ionospheric Alfvén resonator (IAR) and compare the results of electromagnetic waves passing through IAR to Earth's surface with the dynamic spectrum of simultaneous observations of spectral resonance structures ...

Epitaxially Integrated Electro‐Optic KNbO3 Thin Films on Silicon

Advanced Materials, EarlyView.
We demonstrate the first epitaxial integration of electro‐optic KNbO3 thin films on silicon using suboxide molecular‐beam epitaxy. Combining adsorption‐controlled molecular‐beam epitaxy, advanced characterization, and phase‐field modeling, we demonstrate phase‐pure crystalline films mirroring bulk crystals with robust Pockels response, enabling future ...
